Bolivia: Apolo, 4800', Feb. 24, 1902 (Williams No. 4 02). — Resembles B. lucida. A

 fruit- crests". 



8. B. Whitei (Rusby) Niedenzu. — Banisteriopsis Whitei Rusby in Mem. New York 

 Bot. Gard.VH. (1927) 274. — "Grayish-pubescent throughout, the brightgreen upper leaf- 

 surfaces sparsely so. Branchlets elongate, slender, terete, sparsely leafy, the leaves 

 opposite, glandulär, stipules not apparent. Petioles 4 — 8 mm long, very slender, the 

 blades 2 — 4 cm long and 1 — 2 cm wide, ovate, with blunt or rounded base and obtuse 

 or acutish summit, entire, thin, softly pubescent beneath and less so above, the venation 

 inconspicuous. Flowers umbellate or occasionally subracemose, the umbels short- 

 peduncled, mostly 8-flowered, the pedicels filiform, about 1 cm long, bracted at the 

 base and 2-bracteolate at about the middle, the bractlets very small, herbaceous. Calyx 

 3 mm broad, 8-glandular. Petals yellow, 5 mm long, obovate-spathulate, concave, entire. 

 Stamens much shorter than the petals, unequal, the filaments subulate, connate at the 

 base, the anthers small, whitish or pale, the connective much thickened. Styles slightly 

 exceeding the stamens, the summits flattened, the stigmas cristate. Ovary pilose. 



Espia, 3500 feet, O. E. White, July 27, 1921 (n. 429)." 



9. B. Williamsii (Rusby) Niedenzu. — Banisteriopsis Williamsii Rusby in Bull. 

 N. York Bot. Gard. VIII. (19 4 2) 97. — "Lower leaf-surfaces and inflorescence puberulent; 

 branches slender, purple, widely branched, the branches recurved; petioles about 6 mm 

 long, biglandular near the summit; blades 6 — 8 cm long, 3 — 4 cm wide, oval, abruptly 

 short-acuminate, mucronate or aristate at the apex, rounded at the base, thick, the 

 secondaries about 6 — 8 pairs, diverging at an angle of about 45 degrees and lightly 

 ascending, prominent underneath, the venation slender, coarsely reticulate; calyx lobes 

 small, triangulär- lanceolate; samara immature in my specimen, oblanceolate, nearly 

 straight, purple, thin, the body white, sharply tuberculate. — Very slender, 1 5' high. 

 Bolivia: Mapiri, 1600', Sept. 15, 1901 (Williams No.809). A part of No. 484 from 

 Tumupasa, 1800', Jan. 14, 1902, is the same. The other portion of my specimen is 

 another species of Banisteriopsis, probably undescribed, but to young for positive 

 determination. — The species above described is well distinguished by its mucronate- 

 aristate leaves".
